Periodic Log Deletion

ASP.NET Zero has built-in periodic log deletion system (*.Application/Auditing/ExpiredAuditLogDeleterWorker.cs). To enable it, go to appsettings.json and set App:AuditLog:AutoDeleteExpiredLogs:IsEnabled to true; (default false)

"App": {
    "AuditLog": {
      "AutoDeleteExpiredLogs": {
        "IsEnabled": true
      }
    }
}

Then periodic log deletion will be enabled.

Periodic log deletion system also has backup implementation. It uses IExpiredAndDeletedAuditLogBackupService to backup deleted items. It's default implementation uses excel to create backup. To enable it, go to appsettings.json and set App:AuditLog:AutoDeleteExpiredLogs:ExcelBackup:IsEnabled to true; (default false). Then deleted items will be stored in the given file path as an excel file.

"App": {
    "AuditLog": {
      "AutoDeleteExpiredLogs": {
        "IsEnabled": true,
        "ExcelBackup": {
          "IsEnabled": true,
          "FilePath": "App_Data/AuditLogsBackups/"
        }
      }
    }
}
